Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

drm/plane: Add COLOR PIPELINE property

2025-11-26T22:03:32+00:00

We're adding a new enum COLOR PIPELINE property. This property will have entries for each COLOR PIPELINE by referencing the DRM object ID of the first drm_colorop of the pipeline. 0 disables the entire COLOR PIPELINE. Userspace can use this to discover the available color pipelines, as well as set the desired one. The color pipelines are programmed via properties on the actual drm_colorop objects.

drm/drm_plane: track color mgmt changes per plane

2023-12-13T20:09:53+00:00

We will add color mgmt properties to DRM planes in the next patches and we want to track when one of this properties change to define atomic commit behaviors. Using a similar approach from CRTC color props, we set a color_mgmt_changed boolean whenever a plane color prop changes.

Add support for pixel_source property to drm_plane and related documentation. In addition, force pixel_source to DRM_PLANE_PIXEL_SOURCE_FB in DRM_IOCTL_MODE_SETPLANE as to not break legacy userspace. This enum property will allow user to specify a pixel source for the plane. Possible pixel sources will be defined in the drm_plane_pixel_source enum. Currently, the only pixel sources are DRM_PLANE_PIXEL_SOURCE_FB (the default value) and DRM_PLANE_PIXEL_SOURCE_NONE.
